alt Hacker NewsRoblox turns a blind eye to child exploitation (whether being creeped on by adults, or being exploited by teens/adults to make games) and makes a fortune out of it. If it weren't online, it'd be illegal and people would be in jail.
Also, Roblox's favourite thing - other than sitting back and rolling in the cash that their playerbase generated for them - is puff pieces in the news talking about how people who make games for them strike it rich!!!! They don't mention that to do so, you first have to become popular amongst millions of competing titles, and the easiest way to do it is to pay them so they'll advertise it for you.
Oh, and the company scrip - Robux - has very, very different exchange rates, depending on whether you want to buy Robux from the company, or you want to get a payout and convert your Robux to real money. They pay a lot less than it costs to buy Robux, further incentivising you to never actually make real money, because your Robux is "worth more" inside the Roblox walled garden. This is on top of the 75% cut they take!
In all, approximately 17% of the real-world money paid into Roblox is paid back out to creators. What a scam.
